| Abstract: | Heck reaction was employed to synthesize stilbene derivatives by utilizing 1,3-divinyl-1,1,3,3-tetramethyldisiloxane(DVS) as the ethylene source. The effects of the starting material molar ratio, reaction temperature and reaction time on the yield were investigated. A possible reaction mechanism was proposed. The results show that in DMF/H2O at 120 ℃, with the starting material molar ratio of R-Br∶DVS at 5∶1, and reaction time=48 h, the reaction produces 4-vinyl-bis-benzocyclobutene(V-bisBCB) and 1,2-diphenylethene(V-bisPh) with a yield of 45.1% and 48.6%, respectively. |
